ANCHOR FOR CHECK-ROW LINES.

SPECIFICATION forming part 'of Letters Patent No. 236,580, dated January11, 1881.

Application filed September 29, 1879.

T 0 all whom it may concern:

Be it known that I, GEORGE D. HAWORTH, of Decatur, county of Macon,State of Illinois, have invented a new and useful Improvement in Anchorsfor Check-Row Lines or Wires, of which the following is a full andexactdescription, reference being had to the accompanying drawing,making part of the same, and which represents a perspective view ofananchor embracing my improvements.

The invention relates to a novel construction of the anchor forrelieving the check-row line or wire of its rigidity, and permitting themachine or planter operated upon thereby to vary or change its courseslightly from a right line without straining the check-line, while atthe same time holding the latter with a regular or uniform tension; andit. consists in theinterposition of a spring or ayielding arm or clawbarbetween the end of the check-row line or wire and the fixed stake oranchor, as hereinafter explained.

In the accompanying drawing, A represents a fiat bar of metal, forked atone end, and bent into the form of a hook or claw, a, for the receptionand retention of a button or knob, b, on the end of the check-row lineor wire B, as shown. The opposite end of bar A is bent at a right angle,forming a lug or upright, a, which is perforated to receive a slidingrod, 0. The inner end of this rod, overhanging the bar A, is providedwith a collar or button, C, between which and the lug a is a spring, D,surrounding the rod 0, and serving, by its tension, to keep the roddrawn inward over the bar A, as shown. The outer end of rod 0,projecting beyond or outside of lug a, has a loop or eye, 0 formed uponit, through which the stake or fixed anchor E is passed and driven intothe ground, leaving the rod 0 free to swing laterally upon it as apivot, but prevented from escaping therefrom by a loop or head, E,formed upon its upper end.

The operation of the anchor will be readily understood. It is secured inposition, one upon each side of the field, and the check-row lineorwire,-drawn to the proper degree of tension, is stretched between themand secured to the claws a, as explained. When for any reason, such asthe veering of the machine from a right line or an obstruction to themovement of the levers operated upon, an unusual degree of tension isexerted upon the check-row line or wire, the spring D allows the arm orclaw-bar A to yield temporarily, and to slide outward on the rod 0,thereby relieving the strain until the obstruction is passed or themachine resumes its former position relative to the cord or wire andpermits the claw-bar to be retracted by the spring D.

Having, now described my invention, what I claim as new is 1. An anchorfor check-row lines having a spring or yielding connection adapted to beinterposed between said anchor and the checkrow cord or wire.

2. The arm or cla w-bar to which the checkrow line or wire is attached,having a yielding connection with its fixed anchor or stake, for thepurpose specified.

3. The fixed stake or anchor, in combination with the yielding arm orclaw-bar to which the check-line is attached, havinga pivotal connectionwith said stake, substantially as described.

4. The combination, with the stake or anchor E, of the rod 0, spring D,and yielding arm or claw-bar A, substantially as and for the purposedescribed.
